Under most circumstances #242Blue loc-tite holds up very well. With any loc-tite product only a drop is needed, you don't need to liberally coat the threads as some folks think. Doing so is just a waste.
#271Red loc-tite does need heat to remove, and under hot situations will hold up much better than 242Blue. #277Red is much stronger than #271Red. It may get you into trouble if you ever need to remove a fastner in the future. Use it with caution.
These observations are based on me wrenching on Harley-Davidsons for 16 years at various dealerships and independant shops. Harleys are notorious for vibrating and shaking darn near everything loose, especially Panheads, Shovelheads, and Ironhead Sportsters.
98% of all Harleys are on the road...the other 2% made it home.
